Although strong electromagnetic fields decay rapidly, there are still
many novel transport phenomena induced by strong fields that could
be measured in experiments, such as the chiral magnetic and separation
effects [1]}, [2]}, [3]},
the chiral electric separation effect [4]}, [5]}, [6]}, [7]},
and other nonlinear chiral transport phenomena [8]}, [7]}, [10]}, [11]}, [12]}.
These effects can be described by chiral kinetic theory for massless
fermions derived from the path integral [13]}, [14]}, [15]},
the Hamiltonian approaches [16]}, [17]}, the quantum
kinetic theory via Wigner functions [18]}, [19]}, [20]}, [21]}, [10]}, [23]}, [24]}, [25]}, [26]},
and the world-line formalism [27]}. The chiral
kinetic theory has been extended to the massive fermions and with
collision kernels [28]}, [29]}, [30]}, [31]}, [32]}, [33]}, [34]}, [35]}, [36]}.
For reviews of recent developments in this field, see, e.g., Refs.
[37]}, [38]}, [39]}, [40]}, [41]}.
